Description

A kind of lock bolt

Technical field

The utility model relates to a kind of lock bolt.

Background technology

The door-plate of Zhi Zaoing has three kinds of specifications now: circular mortise, the square mortise of tip-angled shape, the square mortise of fillet shape, square mortise 72b of tip-angled shape as shown in Figure 3 and the square mortise 72c of fillet shape as shown in Figure 4, and the lock bolt of general plant produced and panel are composition and its combination inconvenience dismounting that matches, when causing the collocation of the lock bolt bought and panel and door-plate not to be inconsistent, and be difficult to use this lock bolt.

The utility model content

The purpose of this utility model is to provide a kind of lock bolt, and it can provide for simple replacement of the preposition square panel of lock bolt that is fit to the door-plate installation.

To achieve these goals, technical solution of the present utility model is: a kind of lock bolt, comprise housing and panel, the inside of this housing is equiped with plunger latch head, the front end external diameter position of this housing is formed with a projection, this lock bolt also comprises sub-panel, and this sub-panel has extended axially tube wall, and this tube wall is installed on the front end external diameter position of housing; The tube wall of this sub-panel is provided with axial elongated slot and the transverse groove that engagement is installed for the projection of housing, and this axial elongated slot is connected with transverse groove, and this panel has the latch hole that wears for plunger latch head.

Described a kind of lock bolt, wherein the tube wall of sub-panel further has axial short groove, and this axially short groove is connected with this transverse groove.

After adopting such scheme, the combination of the utility model lock bolt housing and panel by with the detachable aggregate erection of sub-panel, provide client can freely replace square panel, the easy adjustment makes the user can select the square panel that is fit to door-plate simply and easily for use, thereby realizes combining of lock bolt and door-plate.

The specific embodiment

Now cooperate graphicly, the preferred embodiment of the utility model lock bolt be described as follows:

As shown in Figure 1, a kind of lock bolt of the utility model comprises: housing 1, square panel 6, and sub-panel 5, wherein:

Housing 1, its front end is equipped with plunger latch head 12, the rear end is equipped with the lock bolt operating mechanism, plunger latch head 12 can be via the effect of lock bolt operating mechanism, from one forward extended position move to a retracted position (detailed manner of execution have technology not give unnecessary details for practising) backward in this, and be outward extended with a pair of up and down corresponding two projections 13 (only showing one among the figure), and has groove 11 in the leading edge of housing 1 in housing 1 front end tube wall;

The lock bolt operating mechanism is placed in housing 1 inside, and its combination kind of drive has structure for practising, and repeats no more in this.

Sub-panel 5, in having extended axially tube wall 52, it can be installed on the front end external diameter position of housing 1.

Axially elongated slot 53 is arranged on the tube wall 52 of sub-panel 5.

Transverse groove 54 forms on the tube wall 52 of sub-panel 5, is connected with axial elongated slot 53 and forms.

Axially short groove 55 forms on the tube wall 52 of sub-panel 5, is connected with transverse groove 54 and forms, for the installation engagement of housing 1 projection 13.

Axially elongated slot 53, transverse groove 54 and axially short groove 55 are communicated with the slotted eye of the L type of formation, and the slotted eye of two L types can be set on tube wall 52 when implementing.

Square panel 6 has the latch hole 61 that wears for plunger latch head 12.

As Fig. 1 and shown in Figure 3, when desire is installed on door-plate 7 with square tip-angled shape panel 6, as long as the projection 13 of housing 1 is aligned axial elongated slot 53 insertions of sub-panel 5 tube walls 52, move along transverse groove 54 again, be sticked at last in the axial short groove 55, housing 1 and sub-panel 5 are combined into one, housing 1 is inserted in the boring 73 of door-plate 7, pass the hole 62 of square panel 6 and the hole 56 of sub-panel 5 with the screw (not shown) then, and square panel 6 and sub-panel 5 are locked in the side of door-plate 7.

In like manner, as Fig. 2 and shown in Figure 4, if desire is installed fillet shape square panel 6a, method is the same to be repeated no more in this.
